In the olden days when we drove to other places we sometimes ate at the casino. Neither of us gambled (or even wanted to) but the food was pretty good and very affordable. Actually the service was fast too - presumably because they didn't want customers to stop throwing money away.It's sort of funny, but when my friend worked at them they had regulars who did buy drinks, or food if available. I think it's sort of like casinos. Some aren't interested in the gambling too much but they go along for the cheap food and drinks; similarly the strippers are like background noise. That sounds awful but it's sort of like ignoring the house band you're not interested in. I think some men bring their dates there who couldn't care less. Some wives go along to appease their husbands. I've been because I knew people who worked at them years ago.
My mom and step dad went to Vegas on a tour of two States - too see the Grand Canyon - stayed overnight or maybe 2 nights, right beside a big casino, and they didn't gamble. (I mean - I don't like gambling because the house always wins, but still, that's weird!)
